    Male ♂   Female ♀
    Its underside surface of the wing has a shape somewhat like bright amber colored leaf, which one is accustomed to at fall; afford it a measure of camouflage in the low growing foliage which it likes to inhabit. Their undersides have an uncanny resemblance to a dead leaf, effectively hiding the rich orange upper side.   It is similar as the male.

    Habitat  
      This butterfly occurs everywhere up to elevations of about 4 500 feet, but is by no means common. It exists mainly in the Uva Province.  
         
    Habits  
     

    It flies extremely quickly but often be seen on the sunny side of any jungle path, sitting proudly upon a leaf, and not moving unless really compelled to. Although the Autumn Leaf is not a shy butterfly, it is impossible to spot unless it is basking on the upper side of a leaf.
